Abstract

Cette invention a trait à un procédé de production d'une poudre d'oxyde, consistant à maintenir à l'état fluidisé une poudre de matériau de base renfermant un premier oxyde et possédant une teneur en eau adsorbée comprise entre 0,1 et 50 %, une taille particulaire moyenne comprise entre 0,005 et 0,5 νm ainsi qu'un nombre de groupes hydroxy de surface compris entre 0,1 et 25 νmol/m2, à mettre en contact la poudre de matériau de base maintenue à l'état fluidisé avec un halogénure ou un alcoxyde contenant un métal ou un semi-métal, identique au premier oxyde ou différent de celui-ci, en même temps qu'avec un gaz vecteur inerte tout en chauffant à une température comprise entre 25 et 800 °C, afin de recouvrir la poudre de matériau de base d'un film d'enduction renfermant un second oxyde et ensuite à chauffer à une température comprise entre 200 et 1000 °C les sous-produits de réaction comprenant un halogénure d'hydrogène ou un alcool formé par la mise en contact susmentionnée et ce, afin d'extraire les sous-produits. On peut utiliser ce procédé pour former, par voie chimique, à la surface de la poudre de matériau de base constituée d'un premier oxyde, un film d'enduction comprenant un second oxyde identique au premier ou différent de celui-ci et ce, de façon homogène et à faible coût de revient et, partant, pour produire une poudre de matériau de base ainsi qu'un film d'enduction aux caractéristiques physiques et chimiques satisfaisantes.
